鲜红斑痣的皮肤分光光度测量与评价

目的　采用反射皮肤光度计测定鲜红斑痣患者的皮肤黑、红色指数 (M Index、E Index) ,了解鲜红斑痣的程度 ,以期对治疗作出评价。方法　随机选择鲜红斑痣患者 2 0例 ,取病灶对侧正常皮肤作为对照。采用皮肤光度计多点测量 ,计算均数。每位病人于氢波光光动力疗法 (PDT)治疗前、后逐次测量 ,绘图描记。结果　正常皮肤平均M Index为 (36 .18± 6 .45 ) % ,E Index为 (1.39± 4.85 ) % ;病灶的M Index为 (4 4.85± 6 .6 1) % ,E Index为 (13 .0 5±6 .30 ) % ;经治疗 1次后病灶的M Index为 (4 1.0 0± 5 .30 ) % ,E Index为 (9.0 4± 4.98) %。经检验 ,正常皮肤的M指数与病灶M指数有统计学差异 ,正常皮肤、病灶经治疗 1次后的E Index均有差异。结论　正常皮肤与病灶皮肤在黑白色度上存在差异 ,但是病灶在治疗前后黑白指数无明显改变。而红色指数在正常皮肤、病灶及经治疗 1次病灶组均有差异。治疗前后对比 ,E Index指数呈下降趋势 ,表明PDT治疗有效。皮肤光度计有定量判断鲜红斑痣疗效的作用

Derma Spectrometer Measurement for Port Wine Stain

OBJECTIVE:Twenty cases of PWS were measured by means of Derma Spectrometer with the goal of estimating PWS condition. MATERIALS AND METHODS: Twenty patients of PWS were chosen randomly in this study. Derma Spectrometer was used to detect lesion and control sides pre- and post- laser treatment. RESULTS: The mean normal skin's M-Index was (36.18+/-6.45)%, E-Index was (1.39+/-4.85)%. Lesion's M-Index and E-Index were (44.85+/- 6.61)%, (13.05+/-6.30)%. Lesion's M-Index and E-Index after one treatment were (41.00+/-5.30)% and (9.04+/-4.98)%. Significant difference existed between normal and lesion's M-Index. Also there were difference among normal skin, lesion and lesion treated. CONCLUSION: There is difference between normal and lesion M-Index. But none for lesion and lesion treated. Different E-Index were among normal skin, lesion and treated lesion. The E-Index was decreased at treated lesion. It suggested blanch of PWS after laser treatment. Derma spectrometer has the role of evaluation of PWS.
